7 new and useful'lmprovements in Reversible- Sheet-RegisteringMechanism, of which the following is a specification.

This invention relates to sheet registering means for paper handlingmachines, and has for its rimar ob'ect to rovide im roved means forregistering a sheet by gaging some other than the forwardly presentededge thereof. The preferred embodiment of my invention shown on thedrawings contemplates a suitable arrangement of a gage to register asheet according to its rear edge. In some forms of folding machines, ithas been found desirable in order to meet certain trade requirements, tofeed the sheets with their usual gaging edges reversed in position withrespect to their direction of movement through the machine. In order tomeet the requirements of these conditions in a simple and economicalmanner, the present invention contemplates, for example, having theusual gage edges of the sheets reversed, each of said sheets being fedto the machine in a plane different from that in which the reverse gageis stationed and afterward moved into the plane of said gage whichthereupon aids in registering the sheet. More specific objects ofinvention will appearin the specification and be pointed out in theappended claims, reference being had to the drawing which shows areferred embodiment ofmy invention in si e elevation, parts being brokenaway and part shown in section.

Referring more particularly to the drawing, and to the embodiment showntherein, a frame 1 of a'folding machine is provided with a cross rail 2'to which are rigidly se- 7 cured irregularly shaped brackets 3 whichcarry extensions at to which is mortised the forwardly presented edge ofa feed board 5. Journaled within the brackets 3 is a feed roller shaft 6which carries feed rollers 7, suitable drop rollers 8 being journaled inspaced arms 9 which oscillate about the axis of a rock shaft 10 which isjournaled in upwardly extending bracket arms '11. Sheets which are fedone by one to the rollers 7 and 8, are delivered to endless feed tapes12 which pass by the rollers 7 and have the upper runs thereof travelingtoward the left according to the drawing, under the guide rollers 13,around the guide rollers 14, and having their lower runs travclingtoward the right. Suitable stops 16 are mounted on a transverse rod 17which are carried by suitable nuts 18 threaded on oppositely arrangedfeed screws 19 by means of which said stops 16 may be moved to and froto meet the requirements of different sized sheets which may be fedthrough the machine. The screws 19 are journaled in suitable brackets 20and provided on their outer ends with bevel gears 21 meshing with bevelgears 22 keyed to a transverse shaft 23 which may be provided with acrank for effecting the changes in position of the stops 16. As eachsheet is fed forwardly by'the upper runs of the tapes 12, the forwardlypresented edge (not the gaging edge) is intercepted by the stops '16,the plane of travel of the upper runs of V horizontally and secured inany desired position by means of the thumb nuts 26which' bind it to across bar 27 The cross bar 27 is mounted on laterally spaced rods 28carried by bracket arms 29 which are coaxially mounted with the rockshaft 10. The oscillatory movement of the rods 28 and hence of the gages24 may be imparted by the drop rollers, operating mechanism or by anyother suitable means (not shown on the drawing). Laterally displacedwith reference'to the feed tapes 12 are a plurality of sheet engagingbars or rods 30 provided with inclined slots 31, the walls of which are'in slidable engagement with suitable pins 32 which raise and lower thebars 30 as they are reciprocated by means of yokes 33 rigioo ed on theframe 1. A lever arm 42 which is keyed to the rock shaft 36 has one endpivotally connected to a spring rod 43 which retains the cam roller 38in running contact with the cam 89. It will be understood from thisdescription that while the drop rollers 8 are feeding a sheet onto thetapes 12, the sheet gages 2% are elevated to permit the sheet to passwithout obstruction. During the same interval the cam 39 is retainingthe rods or bars 30 in their left hand position so that their uppersheet engaging surfaces are disposed below the plane of the sheet. Asthe drop rollers are lifted, the sheet gages 24 are lowered and when thecam roller 38 has dropped to the inner run of the cam 39, the rods orbars 30 are moved toward the right, and guided upwardly by theengagement of their inclined slots 31 with the pins 32 to lift the sheetfrom oil the tapes 12 while at the same time imparting a retrogrademovement thereto which brings their gaging edges (disposed toward therear) against said gages 2%. The lateral displacement which is impartedto the sheet '(means for this movement not being shown on the drawing)completes the register of the sheet which then continues its movementthrough the machine.

I claim:

1. In sheet-registering mechanism, means for feeding a sheet forwardlyinto position to be registered, means for terminating the forwardmovement of said sheet, and means for imparting a retrograde movement tosaid sheet to bring it into registered position, said retrogrademovement means being adapted to move the sheet out of engagement withthe forward movement feeding means.

2. In sheet-registering mechanism, means for feeding a sheet forwardly,means for intercepting said sheet in its forward movement, asheet-registering gage outside the plane of said forward movement andpast which said sheet is fed during its forward movement and means formoving said sheet out of the plane of its forward movement into a planeof movement including said gage, the last-mentioned means being adaptedby its movement to move the rear edge of said sheet against said gage. V

3. In sheet-registering mechanism, means for feeding a sheet forwardly,means for intercepting said sheet in its forward movement, asheet-registering gage past which said sheet is fed during its forwardmovement, and means for imparting a retrograde movement to said sheet toregister the same against said gage, said retrograde movement meansbeing adapted to move said sheet into a different plane of movementwhile registering it against said gage.

4;. In sheet-feeding mechanism, sheetfeeding tapes, a stop disposed inthe path of a sheet moved by said tapes, a sheet-registering gagedisposed above said tapes, and sheet-engaging means having a combinedupward and rearward movement for lifting said sheet from said tapes andmoving it into engagement with said gage.

5. In sheet-feeding mechanism, sheetfeeding tapes, a stop whichintercepts a sheet fed by said tapes, a sheet gage disposed above saidtapes, and means normally disposed below the plane of said tapes butadapted to lift said sheet from said tapes, said means being adapted byits lifting movement to move said sheet into a plane of movement whichis intersected by said gage.

6. In sheet-feeding mechanism, sheetfeeding tapes, a stop whichintercepts a sheet fed by said tapes, a sheet gage disposed above saidtapes, and means normally disposed below the plane of said tapes butadapted to move said sheet upwardly into a plane of movement in which itwill be intercepted by said gage, said means rising above the plane ofsaid tapes in its movement toward said gage and falling below the planeof said tapes in its movement away from said gage.

T. In sheet-feeding mechanism, sheetfeeding tapes, a stop disposed tointercept a sheet fed by said tapes, a sheet gage disposed above theplane of said tapes, sheetengaging bars reciprocable between said tapes,and means operated by the reciprocatory movement of said bars forelevating said bars to lift a sheet from said tapes and move it againstsaid gage.

8. In sheet-feeding mechanism, sheetfeeding tapes, a'stop disposed tointercept a sheet fed by said tapes, a sheet gage disposed above theplane of said tapes, and sheet-engaging bars reciprocable between saidtapes and adapted to move the rear edge of said'sheet against said gage,said bars being provided with means for elevating them bodily duringtheir movement opposite to that of the tapes.
